Like any camera, A57 has its strength and weakness. As a photographer you should learn to handle it. In my assessment A57 has two glaring weakness: 1) agressive auto ISO (jack up ISO too soon), 2) prone to mis-focus and lack of any adjustment access. The second problem could be solved when you shop your camera carefully, the fist problem can be solved by using more manual ISO, that's what the EVF is good for (you see the preview of exposure). If you do the right thing A57 will reward you with nice images, even in low light.

Great pictures. Here are mine. Same people, same position, one has ISO 1250, one ISO 1600.



Big Windows, plenty of light, as it can be seen.

Plenty of light perception is due to Center Spot Metering in use. The brightness value of the scene otherwise looks typical of the indoors (+2 or so). This also explains the 1/3 stop difference in ISO as the composition is different just enough for it.
